二、可数名词与不可数名词
名词按其所表示的事物的性质可分为可数名词和不可数名词。可数名词表示可以用数目计数的单词;不可数名词表示不能直接用数目计数的单词。
1. 可数名词和不可数名词的用法区别
可数名词有单数和复数两种形式，而不可数 名词只有单
数形式。
pen →pens 钢笔（可数）
bread 面包（不可数）
(2) 不定冠词a/an、基数词可直接修饰可数名词，表示数量；
而不可数名词在表示数量时, 则用“冠词/基数词+表示计
量单位的名词+of+不可数名词”。
an apple 一个苹果
a piece of bread 一片面包
four cups of water 四杯水
(3) 可数名词复数前可用many, some, any, few, a few, a lot
of, lots of等修饰；不可数名词 前可用much, some, any,
little, a little, a lot of, lots of等修饰。
many teachers 许多教师
much money 许多钱
(4)可数名词作主语时，谓语动词与主语的单复数保持一致。
不可数名词作主语时，谓语动词用第三人称单数形式。
注意：当不可数名词前表示计量的名词是
复数时，谓语动词用复数形式。
(5) 提问可数名词的数量用how many，提问
不可数名词的数量用how much。
例句：你有多少本书？
How many books do you have
我们需要多少盐？
How much salt do we need
1 名词复数的规则变化：
(1) 一般情况下在词尾加-s。如：book → books, chair → chairs
(2)以s, x, sh, ch结尾的名词，在词尾加-es。如：
class → classes, box → boxes
(3) 以f或fe结尾的名词，先将f或fe变为v，再加-es。如：
shelf → shelves, wife → wives
(4) 以o结尾的名词，词尾加-es或-s。如：
tomato → tomatoes, photo → photos
(5) 以辅音字母加y结尾的名词，先将y改为i，再加-es。如：
baby → babies, factory → factories
2 名词复数的不规则变化：
(1) 元音字母发生变化。如：
man → men, woman → women, foot → feet,
tooth → teeth, mouse → mice, goose → geese
(2) 单、复数形式相同。如：deer, fish, sheep, Chinese, Japanese
(3) 词尾发生变化。如：child → children
(4) 有些名词只有复数形式。如：clothes, trousers, people
(5) man, woman修饰其他名词时，单复数要与被修饰的名词保持一
致。如：a man doctor → men doctors
